SRP Distinguished Lecture Seminar Showcases Dr. Barry Dellinger's Research

Barry Dellinger, Ph.D., Patrick F. Taylor Chair, Professor of Chemistry, and Director of the LSU Interdepartmental Environmental Co-operative, presented his research,"Environmentally Persistent Free Radicals: A New Paradigm for the Toxicity of Fine Particles" at the NIEHS (RTP, NC), Wednesday, December 17th.

 

Dr. Dellinger spoke of his discovery of persistent free radicals (PFRs) — newly detected molecules that form on airborne nanoparticles and other fine particle residues as gases cool in smokestacks, automotive exhaust pipes and household chimneys. PFRs can linger in the air and travel large distances. Once PFRs are inhaled, Dr. Dellinger suspects they are absorbed into the lungs and other tissues where they contribute to DNA and other cellular damage. This discovery is a potential explanation for the 10-15% of lung cancers that cannot be attributed to smoking and have been linked to exposure to air pollution.

Duke University CEHI Receives EPA EJ Achievement Award

Duke University's Children's Environmental Health Initiative (CEHI) was one of recipients of the first annual EPA Environmental Justice Achievement Award. The CEHI, partially funded by SRP, is a community partnership that helps reduce the risk of lead poisoning among children in North Carolina. The award cites CEHI for its work since 2002 to promote early intervention strategies to prevent lead poisoning, particularly its efforts to develop and distribute a new mapping tool that public health agencies and community advocates can use to identify households where children are most at risk.

 

On October 21, 2008, CEHI Director, Marie Lynn Miranda, accepted the award on behalf of the partnership in Atlanta, GA. Twelve organizations received recognition, and represented on of five categories: academic institutions; community-based organizations; non-governmental and environmental organizations; state and local government organizations; and tribal government and indigenous organizations. Duke's CEHI was one of three academic organizations recognized.

 

The tool for which the CEHI achieved this prestigious EPA award was the Childhood Lead Exposure Risk Model. The model uses advanced spatial and statistical analysis of data from county tax records, the U.S. Census, and blood lead screening tests to create secure, Web-based maps that predict lead exposure risk levels on a house-by-house scale. The model also allows local health departments to enter new data, search maps, and create reports according to specific local criteria.

Boston University (BU) SRP Links Breast Cancer with Massachusetts Military Reservation

BU SRP researchers have found that women who lived in Falmouth and Mashpee Massachusetts from the late 1940s through the 1950s were twice as likely to develop breast cancer in their later years (1983-1993).  This area is close to the Massachusetts Military Reservation, where contaminants were found in the groundwater; as a result, the military paid for the affected properties to be linked to the municipal water supplies.

 

Researchers are quick to respond that they are not making claims of exposure.  Veronica Vieira, assistant professor of environmental health at BU's School of Public Health, insists that "[researchers] are not trying to make any claims of exposure...there's nothing conclusive..."

 

BU researchers hope that their "time-and-space" analysis can lead to future studies and a more decisive conclusion.  Scientists are looking for additional risk factors, such as geographic and historic patterns, This new study is causing waves because it looks at the smaller (lower) geographic area, yet still tries to pinpoint specific areas of the Cape with a higher than expected numbers.

 

BU's next step:  to use computer software to map the locations of plumes of contaminated groundwater dating back 20 years.

SRP Grantees Participate at EPA FIFRA's SAP on Chloropyrifos

SRP grantees, Drs. Kirby C. Donnelly, Texas A&M University, and Theodore Slotkin, Duke University, were nominated to serve as Panel reviewers for the Environmental Protection Agency (EPA), Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), Scientific Advisory Panel. The Panel convened in Arlington, Virginia on September 16-18 2008 to review the EPA's evaluation of the toxicity profile for the pesticide chloropyrifos, a neurodevelopmental toxicant and one of the most widely used organophosphate pesticides. Exposure to chloropyrifos can occur through food, drinking water exposure, and via residential/occupational applications; the human and ecological risks it poses are historically known. Currently, the Agency is focusing their studies on the effects of chlorpyrifos related to infants and children from in utero and/or post-natal exposures, and on studies that evaluate population variability with respect to chlorpyrifos response.

SRP-alumna, Anne Spuches, Ph.D., Presents Research Results on Arsenic Toxicity

Anne Spuches

 

Former SRP Dartmouth graduate student and Wetterhahn awardee, Dr. Anne M. Spuches, will be presenting her current research at the NIEHS weekly environmental health science series, Frontiers in Environmental Science. Currently, Dr. Spuches is not only an assistant professor at East Carolina University's Department of Chemistry, but also manages her laboratory, while conducting research focused on arsenic toxicity. Dr. Spuches' September 19, 2008 lecture (10 am), "Mechanisms of Arsenic Toxicity: A Thermodynamic and Spectroscopic Investigation of Arsenite and Monomethylarsenite Binding to Small Thiols and the DNA Binding Domain of Glucocorticoid Receptor," will be hosted by Dr. William Suk, M.P.H., at the NIEHS Rodbell Conference Center, Building 101.

 

Recently, Dr. Spuches' research showed that MMA is capable of displacing zinc from the DNA binding domain of the Glucocorticoid receptor, while inorganic arsenite causes no change. These results correlate to studies that show that MMA is more potent and toxic than inorganic arsenic. Her Dartmouth College colleagues, who are SRP-funded, are also working on the full length protein, and have identified the same result as seen in Spuches work. In the future, Dr. Spuches hopes to learn why MMA is so potent.

Dartmouth Workshop Sets Research Agenda for Environmental Mercury

In November 2006, members of Dartmouth's Toxic Metals Research Program convened a group of 43 scientists to set research priorities and a biomonitoring agenda related to how mercury moves through the marine ecosystem and into the fish that we eat.

 

The workshop, "Fate and Bioavailability of Mercury in Aquatic Ecosystem and Effects on Human Exposure", took place in Durham, NH, with funding provided by the NIEHS SRP and support from the New Hampshire SeaGrant Program. The workshop focused on three major themes:

 

  1. the biogeochemical cycling of mercury in marine ecosystems;
  2. the mechanisms of mercury transfer in the food web; and
  3. the risk of human exposure of mercury from seafood and shell fish consumption.

 

This month (August 2008), co-authors Celia Chen, research associate professor of biology at Dartmouth, and Nancy Serrell, director of outreach at Dartmouth, released the research agenda from the 2006 workshop, in the current online issue of Environmental Health Perspectives, "Methylmercury in Marine Ecosystems: From Sources to Seafood Consumers - A Work Group Report".

 

Future efforts related to the accumulation of mercury in the environment include convening workshops to compile and evaluate existing mercury data in marine environments and seafood.

Louisiana State University (LSU) SRP Chemist Isolates Air Pollutants

 
Dr. Barry Dellinger
Dr. Barry Dellinger

Louisiana State University (LSU) SRP

 

Louisiana State University (LSU) SRP grantee and environmental chemistry professor, Barry Dellinger, Ph. D. , received the prestigious Astellas USA Foundation Award for his scientific contributions related to improving public health research. The award was presented to Dr. Dellinger at the Presidential Symposium of the 236th National Meeting of the American Chemical Society (ACS) in Philadelphia, PA.

 

Dr. Dellinger also presented his research on "environmentally persistent free radicals" (PFRs) at the ACS meeting. His research presentation explained how PFRs are pollutants in the form of microscopic particles that are released into the atmosphere from any flame-producing chemical reaction. Due to the environmental effects of combustion, Dellinger believes that this study could potentially demonstrate why so many non-smokers get lung cancer and other pulmonary diseases. More research is needed before such cancer cases can be linked to PFRs. Evidence thus far depicts that 500,000 Americans die each year from cardiopulmonary illnesses related to 'fine particle air pollution.'

 

Dr. Dellinger emphasized that health risks related to PFRs do not necessarily come from chemicals, but rather from PFRs formed during the chemical combustion processes. PFRs are formed during any combustion process, for example, the burning of coal, fuel power plants, and wood.

 

Scientists used to believe that PFRs quickly died (in a matter of microseconds), but Dellinger's research shows that many of these pollutants can live for days following combustion, and some survive indefinitely (hence the name "persistent free radicals").

Brown University Professor Featured in Discover Magazine

Phil Brown, Ph.D.

Phil Brown, Ph.D., is a leading sociologist in environmental health, a member of Brown University's (BU) Superfund Research Program (SRP) Community Outreach (COC) and Research Translation Cores (RTC), and BU professor of medical and environmental sociology. The August (2008) issue of Discover Magazine highlights Brown's contributions as the man who not only coined the term "popular epidemiology," but also continues to raise awareness of environmental contamination in low-income communities.

 

Brown's work focuses on environmental disasters that impact low-income communities, these disasters are typically defined by the neighborhood's long-term health problems, which are inherently caused by toxins. Brown's advocacy for contaminated communities began in Woburn, MA (1984); his efforts continue today, as he perseveres in his efforts to "champion collaborative action(s) between impacted citizens and the scientific community" (Kaplan).

 

Following Brown's experience in Woburn, his academic concentration shifted from mental health to instructing more interdisciplinary classes that focus on medical and environmental sociology, environmental justice, and contested illnesses. Today, Brown continues to lecture at BU, and also assists environmentally impacted communities in the role of advocate or scientist, as needed. Brown is able to utilize his knowledge of political science, toxicology, epidemiology, and sociology, as he applies it to each individual community.

 

More information on Brown's work and influence, The Lifesaving Work of the Man Behind 'A Civil Action   is available in the August edition of Discover Magazine, along with current biological and project data, COC and RTC , on the SRP web site.

UA SRP Receives US EPA Pollution Prevention Grant

Eric Betterton, Ph.D., Ms. Denise Moreno-Ramirez, and Ms. Monica Ramirez, UA SRP, in collaboration with Ms. Ann Marie Wolf, Sonora Environmental Research Institute, Inc. (SERI), recently received a US EPA Pollution Prevention (P2) grant. The purpose of the P2 is to help reduce the amount of hazardous substances entering the environment, conserve energy and water, and improve the community's environmental health.

 

The UA SRP Project Coordinators for the Research Translation and Community Outreach Cores (RTC/COC) see this grant as a product and confirmation of their Outreach diligence. With SRP funding, both UA's SRP and the Binational Center programs were able to build trust with the promotoras (health outreach workers), and support initial nurturing and partnership building with SERI and CASA.

 

Project Coordinator, Monica Ramirez, stated: "Our goal is to effectively communicate the science generated from the UA SRP and Binational Center. We are now partners with strong conduits in the community who are disseminating and utilizing the science of our program to educate others...[We] are building upon a foundation that we have built with the community, which is crucial to carry out the goals of RTC/COC."

 

SERI and the UA SRP will use the P2 to continue developing the Community Assist of Southern Arizona (CASA), emphasizing a P2 program for businesses. UA's SRP has been instrumental in CASA's development; they have served on the advisory board, provided toxicology and environmental science training for promotoras, and technical expertise.

 

With the P2 grant, the UA SRP will:

  • provide training for promotoras, so that they can effectively communicate pollution prevention and source reduction strategies to business sectors;
  • assist in eight workshops that focus on industry-specific source reduction methods;
  • help eliminate barriers to implement P2 programs; and
  • help develop P2 packets for local Tucson businesses on industry-specific measures.

UA's Superfund and Binational Center Program Coordinators Launch CampCIENCIAS, June 16-20, 2008

SRP Binational Center Program

The University of Arizona's SRP and Binational Center is hosting the first CampCIENCIAS (translated, Camp Science) for 20 high school students living on the United States' side of the Mexico border. The concept for this program began with three Latina scientists/program coordinators from UA: Denise Moreno (SRP & Binational Center), Rocio Estrella (Binational Center), and Monica Ramirez (Binational Center & SRP).

 

The students' week-long CampCIENCIAS agenda will include several science-learning activities, in which students will gain skills in science, technology, engineering, and math through hands-on experiences and mentoring sessions with UA undergraduate students. CampCIENCIAS participants were selected as a result of personal essays, which focused on their lives and the reasons they wanted to attend Camp Science.

 

Ramirez, Moreno, and Estrella first presented CampCIENCIAS to their mentor and Binational and SRP program director, Dr. A. Jay Gandolfi. He whole-heartedly supports the trio's goals and aspirations for their community education efforts. With this vote of confidence, the three then applied and received a grant from the UA Technology and Research Initiative Funds (TRIF) via the Water Sustainability Program. The grant will cover the tuition, room and board for the 20 students.

SRP Scientists at Duke Reveal TRI Burden Reduction Rule Flaws

Duke University scientists, funded by the NIEHS SRP, recently published their study, "Environmental Justice Implications of Reduced Reporting Requirements of the Toxics Release Inventory (TRI) Burden Reduction Rule," in Environmental Science and Technology. Scientists found that the vast majority of individuals negatively affected by the 2006 EPA TRI Burden Reduction Rule are minority and low-income communities.

 

The TRI was first introduced to the public in 1986. It protected public communities, health and safety officers, workers, and regulators by alerting them about the presence and/or use of chemicals in, around, or near their living or working vicinity. The altered 2006 TRI Burden Reduction Rule was a rule created to exempt some industries from reporting detailed information about the toxic chemicals they released.

 

Marie Lynn Miranda, director of the Children's Environmental Health Initiative (CEHI) at Duke University, and associate professor at the Nicholas School of the Environment, along with her team, used a distance-based geographic information system (GIS) spatial analysis to examine the racial and socioeconomic characteristics of communities with one kilometer, three kilometer, and five kilometer buffers around exempt and non-exempt facilities.

 

Miranda et. al's results were found to be in discord with the EPA's interpretation of its national analysis. She said that the overall results for those communities within "proximity to industrial facilities [that are] no longer required to report detailed information about their chemical releases, have significantly higher percent minority, minority under the age of five and low-income populations compared to communities where all the information is still available...there was also significant differences in these demographics between regions and at the state level."

 

For the more information on Miranda's research, her publication is available at Environmental Science and Technology  online.

Brown University's SRP Develops Disposal Mechanism for CFLs

CFL on Carpet

Dr. Robert Hurt, professor of engineering, Brown University , and senior engineering student, Natalie Johnson, helped lead Brown's SRP research team in the development of an innovative mechanism to safely help in the disposal of compact fluorescent lamps (CFLs).

 

This break-through is crucial because CFLs contain a small amount of vaporous neurotoxin mercury, which releases vapor when the bulb is discarded. The vapors emitted from the bulb pose serious health risks to infants, children, and pregnant women.

 

The Brown University teams of SRP scientists, engineering students, and Steven Hamburg, associate professor of environmental studies, have collaborated to construct two prototypes using the mercury absorbent materials discovered by Johnson and Hurt. The two prototypes developed: a mercury-absorbent package, which will be placed inside the store-bought CFL package, and plastic bags that are specifically designed to soak up the mercury vapors when the CFLs are thrown away.

 

In early 2008, Brown University applied for federal patents for both the mercury absorption packaging and the absorbent material, nanoselenium. In the near future, the university hopes to talk with potential companies that are interested in manufacturing the new technology.

UA: SRP and U.S. Binational Center Coordinate Promotora Training

The UA SRP and the Binational Center teams helped coordinate the "Fundamentals of Toxicology" workshop for the Community Assist of Southern Arizona and Tucson Unified School District promotoras (community health advocates) on April 19, 2008.

 

The workshop's objective was to increase the promotoras' level of understanding in the fields of toxicology and epidemiology from both Mexican and American academic perspectives. The half day training session was taught by Drs. A. Jay Gandolfi (toxicology) and Mercedes Meza (epidemiology); Ms. Rocio Estrella served as the event translator.

 

As part of the training, participants received copies of the presentations and take-home materials to help reinforce what they learned. Most importantly, the promotoras interacted with a number of UA faculty and staff, so as to encourage communication and expand their professional information resources.

 

This new and unique training program demonstrates UA's Binational Center and the SRP's goal to bridge the gap between the scientists and the public.

University of Arizona's SRP Hosts International Conference on Mine Tailings

The University of Arizona, College of Pharmacy's Superfund Research Program (UA SRP) hosted an international workshop to address mine tailings on June 5-6, 2008. The workshop's 48 global experts converged to discuss health impacts and novel approaches to handle problems related to mine tailings in arid environments.

 

According to the UA SRP, inactive and abandoned mine tailing disposal sites are prevalent in arid and semiarid regions of the world. Monica Ramirez, a member of the workshop's steering committee and coordinator for the UA SRP Research Translation Core, commented that these "mine tailing sites can have profound health and environmental consequences."

 

NIEHS (a major sponsor to the workshop) funds the UA SRP. The school's SRP goal is to "investigate the hazardous waste and public health issues currently confronting the Southwestern region of the United States, specifically arsenic, chlorinated hydrocarbon, and mine tailings contamination."

 

Workshop discussions will help prepare a collaborative white paper journal article with recommendations and results from the meeting.

UK Students Shine at the Society of Toxicology Conference

Zuzana Majkova and Elizabeth (Beth) Oesterling represented the University of Kentucky's SRP Labs at the 2008 Society of Toxicology (SOT) Conference in Seattle, WA. Both were awarded travel awards for their research in the laboratory of Dr. Bernhard Hennig.

 

SOT recognized Zuzana's research efforts for her novel studies in examining the role of caveolae in PCB-mediated toxicity. At the conference, Zuzana presented her poster, "Endothelial Cell Caveolae are Involved in Activation of Aryl Hydrocarbon Receptor Pathway by Coplanar Polychlorinated Biphenyls." Her research demonstrates that certain diet-derived compounds can down-regulate caveolin-1 levels and caveolae function. She is currently exploring the possibility of using a diet enriched in dietary n-3 PUFAs to modulate endothelial caveolae and possibly prevent cardiovascular toxicity. This research can potentially help in uncovering dietary therapies for PCB-exposed populations, and help develop primary prevention strategies of diseases associated with a variety of environmental toxic insults.

 

Presently, Zuzana is finishing her Certificate in Environmental Systems, which will allow her to approach environmental problems from a broader perspective. She will graduate for UK in the spring of 2009 with a Ph.D. in Toxicology.

Beth received a travel award from SOT for her research on the interaction of flavonoids with hydrocarbons. At the Seattle conference, she presented her poster, "Benzo[a]pyrene-Induced Vascular Endothelial Adhesion Molecule Expression Can Be Disrupted By Selective Flavonoid Treatment." Her research focuses on the polycyclic aromatic hydrocarbon, benzo[a]pyrene (B[a]P), and its role in endothelial cell dysfunction in the vasculature.

 

Beth's research also supports the objective of the UK-SRP, which is the incorporation between nutrition and exposure to environmental toxins that lead to disease. She is investigating the role of flavonoids, dietary polyphenolic compounds enriched in fruits and vegetables, in their protection against B[a]P induced vascular diseases; thus far, she notes that select flavonoids will protect against B[a]P induced ICAM-1 expression. Nutrition may provide the most sensible means to develop intervention and prevention strategies of diseases associated with many environmental toxic insults, and can also be used as models for pharmacological interventions.

 

Another research project that Beth is working on is a collaborative project between Dr. Hennig's laboratory (biomedical science specialization lab) and the laboratory of Dr. Bachas (chemical and physical sciences). Jointly, the labs investigate the toxicity of manufactured alumina nanoparticles to the vascular endothelium. Nanoparticles are a billion dollar commercial industry, but, in the recent past, numerous concerns have been raised as to whether these materials are safe. With help of Dr. Chopra (Dr. Bachas' lab), Beth demonstrates that alumina nanoparticles, which comprise 20% of the nanoparticles produced worldwide, can increase the expression of a number of cellular adhesion molecules and increase the activation of the endothelium in an in vitro system. The collaborative nature of the University of Kentucky SRP grant continues to allow these labs to investigate multiple sides of this complicated problem.

 

Presently, Beth is finishing her Ph.D. in Toxicology and will graduate this summer. She hopes to work for the EPA in North Carolina with focuses on the application of research and risk assessment.

EcoArray, Inc. Fosters the Development of a Powerful Fish Gene Database

EcoArray, Inc. combines the expert construction of arrays along with fish gene data, so as to develop products that will test the response of fish genes to environmental stimuli.  Superfund Research Program (SRP) Small Business Innovation Research (SBIR), Phases I and II grants helped EcoArray develop, validate, and market large oligonucleotide-based glass microarrays for fathead minnows and largemouth bass, which, in turn, fostered the development of a powerful fish gene database.  (Note, the launch of the chips developed in compliance with the SRP SBIR grant, and other ‘complementary products,’ were launched beginning in 2006.)

 

Building upon EcoArray’s notable progress in the realm of microassay development, they received the EPA-SBIR Phase I Grant to continue research to identify the gene response (in minnows) following exposure to carbon nanotubes.   This research will then be added to the fish gene database and analyzed to determine the affected [metabolic] pathways, which will help identify the “genetic fingerprints,” and help validate the expediency and affordability of using high density fathead microarrays for compound screening and use in determining environmental toxicity.

 

EcoArray’s ultimate goal is to determine the negative and/or adverse effect(s) that nanomaterials could have on human health by using the fish gene database as a tool to interpret human health issues.

Developing "Smart" Materials for Business and Industry from The Lane Report, Research Kentucky, 2008)

Biologists and chemists from the University of Kentucky's (UK) College of Arts and Sciences are developing new strategies to integrate cell and protein recognition, function, and motion to build nanoscale architectures through business and industry applications.

 

The nanotechnology research teams of Drs. Leonidas Bachas and Sylvia Daunert (Department of Chemistry) have combined their efforts to develop "smart" biomaterials, substances that can sense a stimulus and react to it in a useful, reliable, reproducible, and reversible manner. The combined groups are supported by over $1.5 million a year in federal funding.

 

The UK's research groups are also focusing on biomaterials that integrate proteins within hydrogels, i.e., jelly-like substances that swell or shrink in the presence of a target compound. The swelling or shrinking action of these nanomaterials is important and can potentially translate into applications, such as the fabrication of microlenses for integration into analytical instrumentation for pharmaceutical, environmental, clinical, and biotechnology industries.

 

Other new research items include polymers that open and close valves in devices, microfluidics systems for use in analysis and diagnostics, and responsive drug delivery systems. These applications can potentially be available to the public within the next five years, although the microlenses might appear earlier.

 

Daunert believes that the sensors and microlenses will, most likely, give the Kentucky economy the biggest boost.
